hardware support #3
Comments
No. May be in the future when we'll add support for USB adapters. |
for ch341 i use https://github.com/setarcos/ch341prog |
I think, in case of USB to serial adapters (like PL2303) under Linux it's easy to add into the list, but i don't know, is it equally simple under Windows? |
ch341 has serial and parallel port interface. https://www.onetransistor.eu/2017/08/ch341a-mini-programmer-schematic.html |
Yes, but all old hardware solutions are very simple, without interface to microcontroller. I think, it's better to implement it with libusb. I have bought this programmer on aliexpress, and can begin with tests 3-4 weeks later, after delivery. :) |

Thank you for the links. CH341 (like other chips, for example FTDI) support SPI and I2CBus. |
Hi! |
@eduard-x |
Hello johndoe71rus, |
Hi. Any news about USB? Thank you. |
Hi! |
Hello! From this weekend i will continue to work on this usb extension. Was very busy last months at work. |
Hi! |
Hi!
And i'm getting from PonyProg followed debugging list (project compiled with enabled debug option):
I'm trying to find the find the bug(s), but possible with more eyes we can find this faster :) |
Yes! I can read my 24c16 about the USB in UART mode! :) |
Now i'm busy with additional Interfaces for ch341a: i2c, spi. |
Thanks for the work. Are you going to make software for Windows? |
Yes, after testing of USB integrated driver, libusb is an multiplatform library. But i don't know, what is with exec rights, i think, the program under Win must be start with admin rights. Under Linux is it easier to allow this with udev rules file for users. |
Try to build (lubuntu 18.04) |
You need to install libftdipp1-dev on 18.04 |
i use ch341prog with ch341A only one time to read/write 25q64xxxxx |
WHAT IS HW? COMPLET TEXT, PLIS! |
I found a device with a weird usb serial bridge. defined as ID 1a86:7522 QinHeng Electronics. Google finds device ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter. I found the manufacturer page http://www.wch-ic.com/products/CH340.html similar to ch340k, 10 pin. For download, they suggest the file CH341SER_LINUX.ZIP but I can not build it because of an error. You can also find the file CH341PAR_LINUX.ZIP |
You do not need another driver, just manually load module ch341 and then enter: |
do you think so? |
That's why you have to write it to new_id. |
yep. Exactly this LILYGO board. It work. Thanks! |
@eduard-x Any news on the support of USB adapters for programming EEPROMs? Did you managed to get it working with CP2102? |
I'm intrested too about CH341 support |
does ponyprog support ch341A or PL2303 cheap chips?
thanks
